"2016 is a pure electric vehicle reflection years, but also the global transformation of pure electric vehicle signs year." For the current development of China's new energy vehicle problems, the executive vice president of China's electric car hundred will Ouyang Minggao December 23, In China electric car 100 people will 2017 news conference said.
He believes that at this stage, China's development of electric vehicles, there are a series of challenges and problems, mainly in the charging infrastructure and vehicle development progress does not match, but in the long run, new energy vehicle technology development route from the electric, light Quantitative, intelligent and low-carbon electric energy into a combination of lightweight and eco-manufacturing integration, intelligent and network-based combination.
Especially in the field of electrification, China's goal for the next five years is to further the new positive development of electric vehicles, especially pure electric vehicles with commercial competitiveness.
"The so-called commercial competitiveness, that is, the mainstream A-class cars at home, the cost performance and fuel vehicles competition.Today the world are moving in this direction, such as Tesla Model3, General Bolt, its development goals are driving Mileage of 350 km or so of the electric car with cost-effective. "Ouyang Ming Gao said.
Ouyang Minggao said, but to meet this requirement, the battery must reduce the weight, size and cost. In addition, the specific energy of the battery must be substantially increased to 300-350 watts per kilogram, which is the next step in our power battery business goals.
Power battery costs are expected to drop to
1 yuan a watt hour
"As we all know, lithium-ion battery has been invented only 20 years, lithium-ion battery power in the real use of electric vehicles less than 10 years, the first time in 2007, Nissan hear the wind began to use, showing a very rapid progress in battery power. "Ouyang Minggao said, electric vehicle lithium - ion battery technology progress has exceeded expectations.
However, the mainstream view, pure electric cars with other types of electric vehicles, from the cost point of view, its advantage is mainly reflected in the range of 100 to 150 km mileage, but now with the lithium-ion battery technology, Times, that is, within the range of 300 km, still in terms of cost advantages.
From the technical point of view, in the unit weight, unit volume of energy stored more and more, the cost is getting lower and lower, in order to reflect the level of electric vehicles and technology.
The good news is that China's battery costs can be reduced by about 20% per year. According to reports, five years ago, China's power battery price is 5.5-6 yuan per watt, the average price of 2.5 yuan last year, 2016 2.2 yuan, taking into account a large number of electric vehicles is a bus, the battery price will be relatively Higher.
"Now the domestic development of electric cars, the lowest system cost of 1.3 yuan per watt, the cost of a single piece of money in the United States General Bolt electric vehicles, single cost of 150 US dollars a kilowatt - hour.
According to this standard, 1.3 yuan per watt when the battery system cost in the industry is not yet generally available, but in accordance with the current 2.2 yuan, 10% to 20% reduction by 2020, 1.3 yuan battery system cost price will Will be achieved.
"With recycling to do 1 yuan, that is, a thousand hours of battery within a thousand yuan, it can be done." Ouyang Ming Gao said.
For a cost-effective, you want to have commercial competitiveness of the A-class cars, now about 100 km power consumption of 15 degrees in 2020 is expected to control power consumption within 12 kWh, close to 10 kWh 100 km.
"To achieve this goal, you need to reduce the power consumption by optimizing the overall weight and efficiency of the entire drive system and charging the current power consumption is still much room for reduction.If you can achieve the above objectives, a cost of about 100 km In the ten thousand dollars, if the battery can reach 300 kilometers is thirty thousand dollars, taking into account the use of power-saving and maintenance cycle to save money, will have a commercial competitiveness, which is the next largest electric goal. "Ouyang Ming high Say.
Pure electric drive drive a comprehensive industrial development
"Pure electric drive technology to establish the background of the line began in 2009. pure electric drive real industrialization is in 2014, although the new energy vehicles in 2015 to achieve explosive growth, but still belong to the more extensive development model, this year, electric Automobile development gradually become rational.Overall, come today, the development of electric vehicles in China has made a certain status in the international. "Ouyang Minggao said.
In fact, in 2015 China's new energy vehicle production and sales accounted for the first in the world, as sales of more than 50% of the world over, in the international community has aroused strong repercussions, both the government or manufacturers, have felt the challenge from China's first force . More noteworthy is that in 2016, such as the German Volkswagen and Japan's Toyota, have to adjust the technical route to accelerate the transformation of pure electric drive.
However, pure electric drive the strategic goal is to lead the industry through pure electric drive all types of new energy vehicles in all-round development. For hybrid technology, the traditional automobile power, automobile companies more advantages than our country, such as the Toyota line is to do first hybrid, do plug-in hybrid and fuel cells.
As the lead in the development of pure electric drive, led the development of the battery industry reached the forefront of the world, the battery industry reached the world scale, the overall level of the international top three, the integrity of the industry chain is also the world's first level, Of the battery industry chain, especially the battery materials, such as positive and negative materials, in the international market share of the first.
"On this basis, we are pure electric power system (battery, motor, electronic control) as the base platform, and then the development of hybrid and fuel cell is relatively smooth." Ouyang Minggao said.
According to its introduction, China's plug-in technology has made progress, BYD Qin, Tang, SAIC Roewe 550, and the upcoming listing of the Guangzhou G-MC series-parallel hybrid, either engine, or hybrid devices, are Has made a breakthrough.
At the same time, fuel cell and power battery depth hybrid fuel cell vehicles have also made great progress, the next step will also appear in the international competitiveness of the conventional depth of hybrid power.
"This is a gradual development process, this approach to avoid the early development of electric vehicle industry with foreign manufacturers in the traditional car, especially in the engine and the engine electromechanical coupling devices, such as direct competition." Ouyang said the engine and transmission has been China's auto industry is weak, effective to avoid weak competition, is conducive to the development of China's electric car industry, by 2020, is expected to achieve the Chinese enterprises and foreign enterprises can go hand in hand, synchronous competition.
